Estrogen made by neurons important to making memories

Estrogen in the brain is important to keep neurons communicating and memories being made, scientists report.

Phantom limb sensation explained

After a limb amputation, brain areas responsible for movement and sensation alter their functional communication. This is the conclusion of a new study. The findings may help to understand why some patients report phantom sensations and others do not.

Smartphones help researcher better understand the nature of depression and anxiety

A psychologist’s research using smartphones is providing valuable data in real time, information that could provide treatment benefits for patients struggling with anxiety and depression.

Signals on the scales: How the brain processes images

How are the images cast on the retina reassembled in the brain? Researchers have found that processing of visual stimuli occurs at the earliest waystation on the way to the visual cortex — but not all are treated equally.

How blood vessels protect the brain during inflammation

Researchers have discovered how blood vessels protect the brain during inflammation — a finding that could lead to the development of new treatments for neurodegenerative diseases such as stroke, epilepsy and multiple sclerosis.

EEG helps scientists predict epileptic seizures minutes in advance

A new study shows that acetate, an acid found in some foods, may help doctors intervene when seizures are imminent. Scientists can monitor the brain activity of a specific cell type to predict epileptic seizures four minutes in advance in humans and mi…

Young bone marrow rejuvenates aging mouse brains

A new study has found that transplanting the bone marrow of young laboratory mice into old mice prevented cognitive decline in the old mice, preserving their memory and learning abilities. The findings support an emerging model that attributes cognitiv…

Extinguishing fear memories relies on an unusual change to DNA

Researchers have discovered a DNA modification that enhances our ability to extinguish fear. The findings could help guide the development of new treatments for fear-related anxiety disorders. Professor Timothy Bredy of UQ’s Queensland Brain Institute …

Transcendental meditation can help treat PTSD

New research suggests that practicing transcendental meditation over approximately 3 months can effectively fight symptoms of PTSD and improve depression.

Brain’s primitive sensory region also participates in sophisticated learning

Neuroscientists have revealed that a simple brain region, known for processing basic sensory information, can also guide complex feats of mental activity. The new study involving mice demonstrated that cells in the somatosensory cortex, the brain area …
